Well okay, I was thinking it was a useful factoid if you're planning on using friction to maintain your Z-level on the pipe. But yes, spreading your hands apart also reduces the stress on the hands, as well.

To address some posts that came up while I was playing with inventor, if you're planning on supporting the entire moment of your robot at one rotary joint... Well good luck to you. 225 ft-lbs is pretty significant for a single joint to support.

Also, as I thought my post made clear, don't assume that the tower is indestructible. It is certainly rather sturdy, but it's not nearly as reinforced as it could be. Front-to-back loads will mostly be carried by the joint at the base, with only a little load carried by the frame at the top. So.... I think it's safe(ish) to hang a robot off the side of the tower, but I don't recommend bouncing or anything when you do it.
